Ethernet::begin incompatible with ESP8266 #34

Open GiovanniCmpaner opened 5 years ago

GiovanniCmpaner commented 5 years ago

Currently using void EthernetClass::begin(uint8_t *mac, IPAddress ip, IPAddress dns, IPAddress gateway, IPAddress subnet) generates a compiler error, as IPAddress from the ESP8266 core doesn't have a _address member: https://github.com/esp8266/Arduino/blob/master/cores/esp8266/IPAddress.h

These lines: https://github.com/PaulStoffregen/Ethernet/blob/dbed40a1a308855497dfe3f7a8d8fb5cfdcce2e5/src/Ethernet.cpp#L86-L94

Should be:

W5100.setIPAddress(ip.raw_address());
W5100.setGatewayIp(gateway.raw_address());
W5100.setSubnetMask(subnet.raw_address());

It isn't necessary to check the version, as raw_address() is available since Arduino 1.0.5: https://github.com/arduino/Arduino/blob/22997bbfd5c841a60e9a5909868c62cd459c798d/hardware/arduino/cores/arduino/IPAddress.h

Thanks @GiovanniCmpaner , I would like to confirm that. @PaulStoffregen could you plz implement those changes? Thank you very much! Great work!

Which boards have you tested with this change?

GiovanniCmpaner commented 5 years ago

Any board that uses ESP8266 Arduino Core. As you can see in the source: https://github.com/esp8266/Arduino/blob/master/cores/esp8266/IPAddress.h The class doesn't have a _address variable.
